본 시험은 유기인계 살충제인 Terracur P입제 및 Lebaycid 입제와 유기염소계 살충제인 상감마입제$(\gamma-BHC 입제)$를 수면시용 하였을때 수도요해충인 이화명충, 끝 동매미충, 애멸구 및 흰둥멸구에 대한 동시방제가능성과 방제적기를 구명하고 약제간의 방제효과를 비교코저 실시하였다. 얻어진 시험결과는 다음과 같다. 1) 약제처리후 부화직후 이화명충 접종 시험에 있어서 상감마와 Terracur P는 높은 살충율을 보였으나 Lebaycid의 살충율은 낮았다. 約 $50\%$ 살충력 잔효일수에 있어서 상감마는 8-14日이었고 Terracur P는 6일간이었다. 2) 당초 계획된 방제적기에 관한 정보는 얻을 수 없었다. 즉 주어진 일간격이 좁아 유의한 차를 얻을 수 없었다. 3) 1,2화기 이화명충에 대한 방제효과는 Terracur P=상감마>Lebaycid의 순이었다. 4) Terracur P와 Lebaycid 입제의 처리는 끝동매미충의 방제효과가 좋았으나 상감마$(\gamma-BHC 입제)$의 방제효과는 기대할 수 없었다. 끝동매미충에 대한 Terracur P와 Lebaycid입제의 잔효력은 30일 이상이었다. 5) 애멸구와 흰등별구에 대한 시험은 충의 서식밀도가 낮기 때문에 약제간 방제효과를 얻을 수 없었다. 6) 공시약제중 Terracur P와 Lebaycidd입제는 이화명충과 끌동매미충의 동시방제제로서 사용할 수 있을 것 같다. This experiment was conducted to find out the simultaneous control effect of granulated insecticides on the several major rice insect pests in Korea. The granulated insecticides used were Terracur P$5\%$ (one of the phosphoric insecticides), Lebaycid $5\%$, and Sang-gamma (gamma-BHC) $6\%$. Those insecticides were broadcasted by hand on the paddy field at the ratio of 3kg. in June and 4kg. in August per 10 a, and the date of insecticidal application was based on the maximum moth occurrence of the rice stem borer in 1969. The rice insect pests tested in this study were rice stem borer (Chilo suppressalis W.), green rice leafhopper (Nephotettix bipunctatus cincticeps U.), smiller brown planthopper (Laodelphax striatellus F.), and white back planthopper (Sogotella furcifera H.). For the study of residual effectiveness of the insecticides, the rice stem borer larvae just hatched from the eggs were installed on the sheath of rice plants collected from the paddy field after insecticidal treatment, and the mortality was made at 48 hours after installation. High mortality was observed in Terracur P and Sang-gamma treatments and low mortality in Lebaycid treatment. The duration of residual effects giving about 50% mortality was about 14 days in Sang-gamma and about 6 days in Terracur P treatments. The study on the effectiveness of the insecticides to the rice stem borer in the paddy field was made by the number of dead blades and white heads of the rice plants injured by the larvae, and the number of survival larvae in the straws after crop harvest. The order of insecticidal effectiveness to the rice stem borer was Terracur P=Sang-gamm>Lebaycid. The study on the effectiveness of the insecticides to the leafhoppers and planthoppers in the paddy field was made by the population density by sweeping (5 times) at the given day intervals after treatments. Terracur P was highly effective for the control of the green rice leafhoppers and Lebaycid was moderately effective, but Sang-gamma seemed not to be effective. The effectiveness of the insecticides tested to the planthoppers was not clear, and it seemed to related with the low insect population density. Study on the determination of proper timing of insecticidal application was not also made clear, and it seemed to be short in the range of day intervals in the insecticidal application. For the study on the control effects of the rice insect pests, rice yield per 100 hills per plot was observed. There was no statistically significant difference among the treatments in rice yields, but the order of yield (Terracur P>Sang-gamma>Lebaycid>Control) was paralleled with the tends of control effects above mentioned. In a view point of simultaneous control of the rice stem borers and green rice leafhoppers by the application of granulated insecticides, Terracur P and Lebaycid were more effective than Sang-gamma which have been used.

Backgrounds and Objectives: Vascular dementia is a group of dementing disoders arising from various stroke syndrome. Among these. subcortical ischemic vascular dementia (SIVD) is regarded as a relatively distinct clinical entity. However, MRI patterns of SIVD are not homogenous. In some patients, lacunes are dominant, and in others, subcortical white matter changes are. This study was designed to compare risk factor profiles between SIVD with and without multiple lacunes. Methods: We divided 47 subjects (22 males, mean age. 68 years) recruited from VADAPET (Multicenter Trial For Evaluation Of The Changes In the PET Images Of Subcortical Vascular Dementia Patient) study into two groups one with more than 5 lacunes in deep gray matter (lacune group) and the other with 5 or less(non-lacune group) Clinical characteristics and laboratory findings of two groups were compared. Results: Nineteen of 47 patients (40%) belonged to the lacune group. The lacune and non-lacune groups d d not differ in the following variables: age, hypertension, diabetes mellitus, hyperlipidemia heart disease, history of stroke or TIA, history of trauma or major surgery, family history of hypertension stroke, or dementia, age at diagnosis of dementia, body mass index, white blood cell count, ESR, CRP, fibrinogen, hemoglobin A1C, total cholesterol. LDL cholesterol creatinine, proteinuria, glucosuria, and microhematuria. However, male sex, smoking alcohol. hemoglobin, and HDL cholesterol were possibly associated more with lacune group SIVD than with non-lacune group (p<0 1) Multivariate analyses revealed that smoking, hemoglobin, and HDL cholesterol were independent predictors of SIVD with multiple lacunes Conclusion: Our study suggests that SIVD with multiple lacunes may be significantly different in smoking habits hemoglobin, and HDL cholesterol from SIVD without multiple lacunes.

This study was conducted to examine aspects of skin care of male students at colleges and universities of male students at colleges and universities and its related factors in order to provide informations on skin care for men. The subjects of this study was 600 men who were students at colleges and universities in Daegu City and Kyungbuk Province. Data were collected from May 1, 2002 to June 30, 2002. The results of this study can be summarized as follows. 1. According to the respondents' socio-demographic characteristics, 55.9% of them was 20 to 24 years old and 29.6% was more than 25 years old. 84.9% of them was university students, while 15.1% was college students. 25.3% belonged to the lower class, while 22.4% belonged to the upper class. 52.7% did not have a girl friend, while 47.3% has a girl friend. 41.8% lived in big cities and 48.1% lived in small and medium cities. 2. 63.0% of the respondents replied that they were in good health, while 8.8% of them were in bad health. 41.9% of them was concerned about face and body skin care, while 14.1% was not concerned about it. Among most serious skin problems, the proportion of acne was highest (44.5%). 3. Among the persons who advised the respondents when they selected cosmetics, the proportion of selecting cosmetics as their own will was highest (44.7%). 25.3% of them selected it by recommendation of female family members and 18.3% selected it by recommendation of the girl friend. In the case of selecting it as their own will, the older they were, the higher the proportion was. In the case of having the girl friend, the proportion of selecting cosmetics by recommendation of the girl friend was higher than that of selecting it by recommendation of female family members. 4. 90.4% of the respondents replied that they never visited skin care rooms, while only 9.6% of them replied that they ever visited them. In the case of visiting skin care rooms, the proportion of the upper class was higher than that of the lower class. 5. According to the frequency of visiting skin care rooms, the proportion of once a week was highest (51.0%). 29.4% of them visited them once per 6 months and 19.6% visited them once a month. 6. In the case of the reasons they did not visit the skin care rooms, the proportion of 'no interest' was highest (36.6%). 23.2% did not visit them because they thought the fee for skin care was expensive and 19.5% did not visit them because they thought the skin care room were only for women. 7. In the variables of giving advice concerning skin care, the proportion of 'their own' was highest (29.8%). The proportion of female family members was 28.2% and the proportion of the girl friend was 27.7%. In the case of the age related to having the girl friend's advice, the proportion of 'over 25 years old' was 31.9% and the proportion of '20 years old to 24 years old' was 26.4%. The proportion of 'less than 19 years old' was 23.5%. The older they were, the more they had the girl friend's advice. 8. According to the sources of getting information on skin care, the proportion of mass media (TV, Radio etc.) was highest (36.7%). 26.0% of them obtained them through the girl friend and 13.9% obtained them through female family members. Only 8.4% got them through magazines. 9. The factors influencing the experience of visiting skin care rooms were experience of side effect of foundation cosmetics, concern about skin care, expiration date of cosmetics or checking of directions of using cosmetics, donsideration of skin character when using soap, and regular exercise for health. From above results, it can be concluded that skin care and beauty specialists working in beauty academies or the department of cosmotology at colleges or universities must make efforts to change the negative recognition of male skin care through deep and comprehensive research. It is also necessary to develop systematic education course and institutionalize the qualification management system.

The subjects were 951 premenopausal and 1,167 postmenopausal women who have examined in health promotion center of Yeungnam University Hospital in Daegu city from January, 1999 to Januaty, 2001. The test for bone mineral density. The physical activity and life style were evaluated by questionaire through interview. The results were summarized as follow. 1) The prevalence rates of reduced bone mineral density and osteoporosis in premenopausal women were 23.8% and 1.6%, respectively. However, these values were increased to 46.1% and 28.1% in postmenopausal women. 2) The regular exercise was revealed to have preventive effect for osteoporosis in pre- and postmenopausal women. Among the types of exercise, the most effective exercise was bowling and moderately effective exercise was swimming on prevention of osteoporosis, however, bare hand physical exercise was not significant effect on bone mineral density. 3) The risk for reducing bone mineral density was decreased in women who have higher educational background and income in pre- and postmenopausal. The bone mineral density was highest in white color worker and lowest in blue color worker. 4) The premenopausal women who favor meat were revealed higher bone mineral density than the women who favor vegetable. The women who have drunk none or small amount of alcohol were revealed increased bone mineral density and smoking was a risk factor for osteoporosis. These results suggested that to prevent osteoporosis, the systemized program for promoting anti-osteoporotic factor have to be developed and apply from the thirties whom have maximal bone mineral density.

탈취제로 이용되고 있는 지렁이 분변토로 부터 황화수소를 제거하는 황산화 세균 CP-5를 분리하였다. 이 균주는 운동성이 없고 Gram 음성인 단간균 이었으며, cytochrome oxidase와 catalase test에 양성 반응을 보였다. CP-5 균주는 환원형 황합물을 기질로 하는 배지에서 독립영양적인 생장이 가능하였다. 이 균주는 thiosulfate 에서 tetrathionate를 중간생성물로 하여 최종적으로 sulfate로 산화하고, elemental sulfur를 일단 thiosulfate로 산화한 후, sulfate까지 재산화하는 것으로 사료되었다. 독립영양 배지에 yeast extract 를 첨가하면 균의 생장이 촉진되었다. CP-5 균주 현탁액에 H₂S를 2vvm의 유속으로 주입하면 140ppm까지는 거의 완전하게 제거 가능하였다. 본 연구결과로부터 CP-5 균주는 분변토에서 황화수소를 제거하는 대표적인 탈취균주이며, 황화수소 제거를 위한 생물학적 탈취 공정에 활용 가능하다는 것을 알 수 있었다. A new sulfur-oxidizing bacterium which was capable of degrading hydrogen sulfide was isolated from earthworm casts using deodorant materials. The cell of isolate CP-5 was short rod, gram negative and non-motile, the activities of cytochrome oxidase and catalase were positive. The isolate could autotrophically grow in the basal mineral medium supplemented the reduced sulfur compounds such as thiosulfate and elemental sulfur. This bacterium could oxidize thiosulfate and elemental sulfur to sulfate, and the metabolic intermediates were considered as tetrathionate and thiosulfate, respectively. The removal of hydrogen sulfide by the isolate CP-5 was confirmed, and the CP-5 was regarded as one of microorganisms responsible for degradation of hydrogen sulfide in earthworm casts. The isolate CP-5 can be applied to biodeodorization systems for the improvement of removal efficiency of hydrogen sulfide.

The purpose of this study is to show the influence of congruity with Ads, levels of arousal and operating effect of amount of message information on perception of Ads durations and effects in the traits of background music of radio Ads. In this study, 168 subjects of male and 208 subjects of female were conveniently sampled, and randomly assigned to one of 8 conditions in a 2(congruity, high/low) × 2(amount of information, high/low) × 2(levels of arousal, high/low) factorial design. The results of this study showed that there were main effects of the levels of arousal and amount of information, that is, under the 'condition of low arousal' and 'condition of high congruity condition', there were high scores in the Ad duration the longer. Under 'high congruity condition', there were high scores in the Ad effects consistently, only in the purchase intentions there were interaction effect between amount of information and congruity, therefore operation effect of information was confirmed. There was marginal interaction effect between congruity and amount of information in the Ad effects. Also, there was main effect in the brand attitude, that is, under 'high arousal condition', subjects had the more positive attitude but it is contrary to the hypothesis. And under 'high amount of information', subjects had the more positive attitude in the brand attitude, but it is the results not to be expected by the hypothesis. Finally, implications, limitations and further research about this study were discussed.

This study was performed to investigate the effect of composition changes in glasses on the strength and shade of glass-infiltrated alumina ceramics. Six different borosilicate glasses containing MgO, Li₂O and ZrO₂ in the glass composition were prepared, porous alumina compacts were prepared by slip casting and sintered at 1100℃ for 2 hours. Dense composites were made by infiltration of molten glass into partially sintered alumina at 1110℃ for 6 hours. Specimens were polished sequentially form #800 to #2000 diamond wheel, and the final surface finishing on the tensile side was received an additional polishing sequence through 0.3 ㎛ diamond paste. To evaluate the effect of composition change in glass on the shade changes of glass-infiltrated alumina core ceramics, the color was measured by the CIE L^*, a^*, b^* color scale relative to standard source C. The biaxial flexure strength was measured using the ball-on-three-ball method at a crosshead speed if 0.5mm/min. The color change of composites infiltrated with experimental glasses to In-Ceram Glass AL1 showed that L^* values increased but a^* and b^* values decreased with addition of MgO, Li₂O and ZrO₂ in the glass composition. Maximum color difference of experimental glass-infiltrated alumina core ceramics was obtained in the Group B containing 2.4 mol% MgO in the glass composition. The maximum biaxial flexure strength values 47.41 MPa was obtained in the Group E containing 0.3 mol% Li₂O in the glass composition. The observation of fracture surfaces indicated the microstructurally rough surface with a tendency of toughening by crack deflection and crack bridging.
